Christ, I really can't get 100% accuracy, huh. I should note that since I'm typing random words and not sentences, it also gets me really blur to just type almost blindly when there is no context. When I write real sentences with good structure, and also include numbers and punctuation (Let's try it: Hmm, well 4 294 967 296 is 2^32. 111 x 379 = 42 069. I don't think I'm good with punctuation either? Hmm...) Well, if I type complicated sentences, I used another typing website and it told me my typing speed would be about 90 WPM. So, maybe it depends on what I'm typing and how I feel at that point in time.
If it matters, I currently use Gateron Black switches.
